▎ 摘　　要

NOVELTY - Molybdenum disulfide (MoS2)/graphene/2D transition metal carbide and nitride (Mxene) composite film comprises MoS2 and graphene as the main body of the film, and graphene and Mxene as thin film coating, where the thickness of the film is 100-150 μm. The graphene is graphene oxide. USE - Used as MoS2/graphene/Mxene composite film. ADVANTAGE - The MoS2/graphene/Mxene composite film: is thin, flexible and bendable; has lightweight and controllable thickness; is easy to assemble; has excellent electrical conductivity; and can realize the efficient cycle of lithium battery. The preparation method: adopts electrospinning and electrostatic spraying technology; has good composite effect, simple process and high preparation efficiency; and is economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of MoS2/graphene/Mxene composite film, where polymer, which is polyacrylonitrile (PAN), polyvinylpyrrolidone (PVP) or poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) is used in the method.
